1. "There are no bad foods. If you manage to listen to your body, then the quantity of food and the quality will also change." Bullshit. It's important to listen to your body, yes. But there are very simple bad and totally unhealthy foods, no matter what your body wants or doesn't want and shouldn't be consumed.
2. I have read in many books the chapter "how to grow our own fruits and vegetables", I succeed and I do it, but I am in the minority. And not because others do not want to do it, but they can not do it. You can not do this if you stay in the city, and most people around the world live like this. This should not be a solution, even if it seems interesting, we should put pressure on those who lead us, that the foods we buy to be healthy, not each to grow his own.
